Two-pronged fix for repeated article topics:
1. Feed last 30 days of published article titles into the LLM analysis
prompt with explicit "avoid these" instruction. Zero cost — just
extra context in an existing API call.
2. Replace keyword-overlap dedup (60% word match) with embedding-based
cosine similarity via sentence-transformers/all-MiniLM-L12-v2 on
OpenRouter. Catches rephrasings that keyword matching misses
(e.g. "BPC-157 dosing" vs "how much BPC-157 to take"). Falls back
to keyword matching if the embedding API is unavailable.
Cost: ~$0.00001 per generation run ($0.02/M tokens, ~500 tokens/run).
New files:
- class-semantic-dedup.php — Embedding cosine similarity + keyword fallback
- class-open-router-embedding-provider.php — OpenRouter /embeddings client

Dedup now has two narrow scopes instead of checking all posts ever:
1. Intra-batch: prevents proposing two articles on the same topic
within a single pipeline run (keyword overlap ≥60%)
2. Recent posts: checks only posts from the last 7 days to avoid
back-to-back similar content
Older articles are intentionally NOT checked — revisiting a topic
weeks later is fine. This prevents the dedup from becoming
increasingly aggressive as the blog grows, which was the root cause
of "no viable article ideas found" with 125 collected items.

The old has_similar_post() used WordPress search ('s' parameter) which
matches ANY word in the query. On a niche peptide blog, every topic
shares vocabulary like "BPC-157", "peptide", "dosage" — so all 125
ideas were false-positive deduped against existing posts, producing
zero viable article ideas.
New approach: extract meaningful keywords (strip stopwords), compare
against each existing post title, and only dedup when ≥60% of the
topic's keywords overlap with a single title. Also caches the title
list per pipeline run to avoid repeated queries.
Added summary logging so we can see exactly how many ideas pass
through each filter stage.
